A tensorial form to describe the rheological properties of a rigid triaxial ellipsoid suspended in a Newtonian fluid
2023, Journal of Non-Newtonian Fluid MechanicsSplitting a large pluton by Cretaceous crustal extension: Evolution of the Ziyuan Detachment and crustal thinning of the South China Block
2022, TectonophysicsCitation Excerpt :The new geophysical data unveil the three-dimensional geometry of the Yuechengling-Miao'ershan batholith and the extension of the Ziyuan detachment at depth. In addition, the internal magnetic fabrics of magmatic rocks can reflect flow of melt with or without regional stress, or post-solidus deformation (e.g., Ježek et al., 1994, 1996; Schulmann and Ježek, 2012). Generally, the AMS investigation of plutons will help to reconstruct tectonic superposition in magma-rich orogenic belts (de Saint Blanquat et al., 2011; Žák et al., 2013; Wei et al., 2014a; Ji et al., 2018b; Joly et al., 2009; Talbot et al., 2004).
Crystal clustering in magmas: Insights from HP–HT experiments
2019, Comptes Rendus - GeoscienceCitation Excerpt :This strong fabric is not in accordance with the theoretical fabric evolution predicted by Jeffery's model (Fernandez et al., 1983; Gay, 1968; Jeffery, 1922; Jezek et al., 1994; Willis, 1977). This model, which considers crystals far enough from neighbours to avoid any direct contact interaction or matrix deformation disturbances, predicts cyclic shape fabrics developed by rigid-body rotation of the crystals (Arbaret et al., 2000; Fernandez et al., 1983; Gay, 1968; Jeffery, 1922; Jezek et al., 1994; Willis, 1977). Departure in shape fabric intensity from this model has been observed in 2D analogue (Arbaret et al., 1996; Fernandez et al., 1983; Ildefonse et al., 1992), 3D analogue (Arbaret et al., 2013), and HP/HT experiments (Arbaret et al., 2007).
Mineral lineation produced by 3-D rotation of rigid inclusions in confined viscous simple shear
2016, TectonophysicsCitation Excerpt :Given the main problem and the objective, we narrowed down the large number of simulations needed for a full parametric study by focusing on: (1) finding the value of Wr (confinement ratio, Fig. 2); (2) then on finding whether confinement can make e1 rotate towards the shear direction, by putting e1 in the initial stage at the most critical orientations; and (3) finally analyse the effects of REI's aspect ratio (Ar, Fig. 2) on Wr. Previous 3-D studies investigated the problem of rigid inclusion rotation, but they address infinite shear zones (e.g. Freeman, 1985; Passchier, 1987; Ježek, 1994; Ježek et al., 1994; Ježek et al., 1996). In the present work, the focus is the formation of a lineation in 3-D confined simple shear flow, i.e. not a full parametric study of the 3-D rotational behaviour of REIs in confined flow, which is much more complex and is still under way.
